Speed Pid Control Programming Order - Danfoss VLT AutomationDrive FC 300 Design Manual

Product Introduction
The Speed PID monitors the actual RPM of the motor by using a 24 V (HTL) incremental encoder as feedback. The feedback
sensor is an encoder (1024 pulses per revolution) connected to terminals 32 and 33.

3.4.4 Speed PID Control Programming Order

The following must be programmed in the order shown (see explanation of settings in the VLT
Programming Guide). In Table 3.8 it is assumed that all other parameters and switches remain at their default settings.
Function
1) To ensure the motor runs properly, do the following:
Set the motor parameters according to the name plate
data.
Perform Automatic Motor Adaptation (AMA).
2) Check that the motor is running and that the encoder is attached properly. Do the following:
Press "Hand On". Check that the motor is running and
note in which direction it is turning (henceforth referred
to as the "positive direction").
Go to 16-20 Motor Angle. Turn the motor slowly in the
positive direction. It must be turned so slowly (only a
few RPM) that it can be determined if the value in
16-20 Motor Angle is increasing or decreasing.
If 16-20 Motor Angle is decreasing, then change the
encoder direction in 5-71 Term 32/33 Encoder Direction.
3) Make sure the drive limits are set to safe values.
Set acceptable limits for the references.
Check that the ramp settings are within drive capabilities
and allowed application operating specifications.
